Glad you got it. Didn't know a chipset driver was needed to install Win7 in a 7040. I moved an HDD from a 755 to a 790 some years ago. It was functional, just needed chipset, graphics, and sound drivers.
Sometimes I still learn too. Did you install chipset driver with Win10?
If Win7 won't install via USB, try using a DVD. Then download drivers.
By the way, if installing Win7 via USB, USB 2.0 slot must be used, not USB 3.0. USB 3.0 isn't recognized until USB 3.0 is installed AFTER OS is installed.
There isn't a special "driver" to install Win7 on a 7040.
Re: what do i have to change in bios settings? So i can be able to even boot in windows 7
of course you can boot into Win7. I do that all the time. You need a bootable Windows 7 installation dvd, or a bootable usb installation media of Win 7. The DVD is easier.
no need to change anything in bios. If you use DVD just press F12 at power up to choose DVD boot option.
If you choose to download an ISO file so you can create a bootable file from a DVD or USB drive, copy the Windows ISO file onto your drive and then run the Windows USB/DVD Download Tool. Then simply install Windows onto your computer directly from your USB or DVD drive.
3. Follow the steps in the setup dialogs. You'll have the option to specify where to install the Windows USB/DVD Download Tool.
You must be an administrator on the computer on which you are installing the Windows USB/DVD Download tool. It requires the Microsoft .NET Framework version 2.0 or higher.
Before you run the Download Tool, make sure you have purchased the Windows ISO download from Microsoft Store and downloaded the Windows ISO file to your drive. If you have purchased Windows but have not yet downloaded the ISO file, you can download the ISO file from your Microsoft Store Account.
To make a copy of your Windows ISO file:
1. Click the Windows START button, and click WINDOWS USB/DVD DOWNLOAD TOOL in the ALL PROGRAMS list to open the Windows USB/DVD Download Tool.
2. In the SOURCE FILE box, type the name and path of your Windows ISO file, or click BROWSE and select the file from the OPEN dialog box. Click NEXT.
3. Select USB DEVICE to create a copy on a USB flash drive or select DVD disk to create a copy on a DVD disk.
4. If you are copying the file to a USB flash drive, select your USB device in the drop-down list and click BEGIN COPYING. If you are copying the file up to a DVD, click BEGIN BURNING.
When your Windows ISO file is copied to your drive, install Windows by moving to the root folder of your DVD or USB drive, and then double-click Setup.exe.

Have Secure Boot off in BIOS when loading OS. Turn it back on after OS is bootable.

Re: rufus windows 7 iso
This is how to use Rufus to make a bootable Win 7 installation usb.
If you had already done this, you are good to go.
